I recently moved from Southern Illinois to Green River, Wyoming. It is -20 here and 6200 feet above sea level. A big change from where I'm from. This information may be important or not.

Ok, jeep starts every time when it has sat for hours, when I give it gas in neutral or in gear it begins to stall (choppy) unless I apply more than normal throttle. When I barely apply any gas at all it stalls. When shifting gears it will stall unless I apply more than normal gas. The biggest issue is that once it stalls after initial ignition it will not start again for hours. I haven't checked fuel pressure yet due to the local stores not loaning tools. I don't believe spark to be the problem but y'all are smarter than me. I've read to replace the TPS and I've been told to replace the MAP sensor. First things first I am going to test the fuel rail and replace fuel filter, add some Heet.

I'm not extremely mechanically inclined and I am always a little intimidated by working on vehicles so have some patience with me. Anyways, given these symptoms do you guys think I'm on the right track and do you have any suggestions?

With a cold engine: Take the + battery cable off of the battery. Ground the end of that cable for 30 seconds or so. Stick that + battery cable back on the battery. Start it up and drive it until it gets completely warmed up. That might fix it. I had you dump the learned memory in the brain. You have a big change in atmospheric conditions and your air/fuel mix and possibly your timing was probably wrong for your new climate and height above sea level.

Okay, so I've replaced the fuel filter and someone recommended that I run BG 44k through it to clean the injectors as they believed that to be the problem. It just occurred to me that I am missing a vacuum hose that runs from the fuel regulator to the intake manifold. Though, I am not sure where the hose goes into the intake manifold. Does anyone know if this could be the problem and if so do you have a picture of where it goes into the manifold. I drove the jeep 300 miles today and the cutting out was gone until the jeep sat for an hour. It seems to be worse as the temperatures go cold… I'm not sure where ever vacuum hose is, so I haven't tested for leaks yet.

I've checked it and there is no open spots on the intake manifold so I've got my vacuum hoses mixed up somewhere. It seems the spot w her the fuel regulator should plug into the intske manifold is plugged into a cylinder that is on the lower drivers side of the engine bay. Ill look up an intake manifold vacuum hose diagram
